1. Chapter 8 Labor Mobility
I’m going home
And when I want to go home, I’m going mobile
—Pete Townshend

2. 8.1 Types of Labor Mobility
Job change/no change in occupation or residence
A waiter switches working from Andrew’s Capital Bar and Grill to the Governor’s Club
Occupational change/no change in residence
Much occupational mobility involves changes in closely related occupation.
Example: busboy to waiter.
Each year about 10% of workers change occupation.

3. 8.1 Types of Labor Mobility
Geographic change/no change in occupation
Geographic mobility involves movements of workers from one location to one location.
About 16 to 18% of the population changes residence each year.
Geographic change/change in occupation
About 30% of geographic job-related changes involve a changes in occupation.

4. 8.2 Migration as an Investment in Human Capital
Net Present Value of Migration
Workers will migrate if the net present value of migration (Vp) is greater than zero.

5. 8.3 The Determinants of Migration: A Closer Look
Age
Older individuals are less likely to migrate.
Older migrants have fewer years to recoup investment costs.
Older people have greater firm-specific human capital.
Older people have greater monetary and psychic costs of moving.
Younger people are more likely to have just completed a human capital investment and to “job shop.”

6. 8.3 The Determinants of Migration: A Closer Look
Family factors
The costs of migration rise with family size.
Married people are less likely to move since spouse may hold high wage job.
Psychic costs rise as number of family members rises.

7. 8.3 The Determinants of Migration: A Closer Look
Education
Migration is more likely as education levels rise.
The market for more highly educated workers is regional/national rather than local.
The gain from migration may be greater due to greater variability in workers and positions.
College educated workers are more likely to be transferred and have lower psychic costs to moving.

8. 8.3 The Determinants of Migration: A Closer Look
Distance
The probability of moving falls with the distance the person must move.
Transportation costs will be higher.
Psychic costs will be higher.
Unemployment rates
Families headed by unemployed persons are more likely to move.
The unemployment rate at the origin location positively affects the probability of out-migration.

9. 8.3 The Determinants of Migration: A Closer Look
Other factors that lower migration.
Homeownership
Occupational licensing
High personal taxes at destination location.
Immigration quotas.
Union membership
Foreign language at destination location.

10. 8.4 The Consequences of Migration
Personal Gains
Empirical evidence suggests that the rate of return from migration is 10%
to 15%.
Caveats
Uncertainty and imperfect information
Migration decisions are based on expected net benefits and sometimes don’t occur.
Costs at destination may be higher than expected and earnings may be lower.
Return migration is common and provides information to those at origin.

11. 8.4 The Consequences of Migration
Personal Gains
Timing of earnings gains
Higher lifetime gains don’t necessarily imply the gains occur immediately.
Earnings disparities
Due to a lack of skill transferability across employers or locations, migrants may earn less than similar workers at the destination.
Migrants tend to be self-selected in favor of more motivated workers.
They would tend to have higher earnings than native workers.

12. 8.4 The Consequences of Migration
Personal Gains
The evidence suggests that newer immigrants to the U.S. not likely to ever achieve wage parity than native workers .
Earnings of spouses
A gain in family income from migration does not necessarily imply a income gain for both spouses.

13. 8.4 The Consequences of Migration
Personal Gains
Wage reductions from job losses
A positive return to migration does not necessarily imply higher earnings than would have occurred if past wage rates had continued to be earned.
Example: those moving due to a job loss or political repression.

14. 8.4 The Consequences of Migration
Wage Narrowing and Efficiency Gains

15. 8.4 The Consequences of Migration
External Effects
Though migration has positive efficiency gains, it has positive and negative third-party effects called externalities.
Real negative externalities
These are private actions spilling over to third parties that cause misallocations of resources.
Example: migration to a “boom town” creates congestion and crime.

16. 8.4 The Consequences of Migration
External Effects
Pecuniary externalities
Pecuniary externalities are actions that redistribute income among individuals and groups.
Losses in the origin nation
Output increases in the U.S., but it decreases in Mexico
Exceptions:
Labor is unemployable in Mexico and so output is shared by fewer people in Mexico
Workers send income back to Mexico

17. 8.4 The Consequences of Migration
External Effects
Reduced wage income for native workers
Immigration increases the supply of labor and decreases the wages of native U.S. workers overall.
Immigration decreases the supply of labor in the foreign country and raises wages abroad.
The wages of labor market groups that are gross complements to immigrants will rise, while the wages of while gross substitutes will be lower.

18. 8.4 The Consequences of Migration
External Effects
Gains to owners of capital
The lower wage costs cause owners of capital to gain area cbg.
Feedback effects may eliminate the lower wage costs for labor.
Fiscal impacts
Immigrants may utilize transfer programs than native workers and redistribute income away from native workers.
Recent evidence indicates this is case.

Impact of Capital and Product Flows

20. 8.6 U.S. Immigration Policy and Issues
Legal Immigration to the U.S.

21. 8.6 U.S. Immigration Policy and Issues
Effect of Illegal Aliens

22. 8.6 U.S. Immigration Policy and Issues
Wage Effects of Illegal Aliens
Illegal aliens depress wages in some low skill labor markets.
The impact of illegal immigration on the average wage rate has little net impact since there are offsetting effects.
Illegal immigrants and some types of native labor are gross complements, and so the wage of these native workers will rise.

23. 8.6 U.S. Immigration Policy and Issues
Wage Effects of Illegal Aliens
Illegal aliens are not eligible for public assistance, but some obtain assistance with forged documents.
Most likely illegal aliens are young and don’t meet requirements for assistance and do pay taxes.
Most likely illegal aliens are net taxpayers.
